We are on 4.14.77
I will look at cherry picking the tpm from 4.18
We are currently on Alpine 3.8 hoping to move to 3.9 (for other reasons) and also looking to move to 4.19 kernel.
This is going to take some time, but now I have a greater incentive to push on that.
Thank you all for your help in this.

Looking at ftrace output was odd, because it showed it going into release_locality, and then it would request_locality and see the locality as active, and not try to request the locality. So a patch went into 4.18 to change the release locality code in the tis driver to check that the access register shows the locality as no longer active before returning instead of returning immediately.Ken,No as I explained in the other email, the openssl_tpm2_engine mostly
Doug, are you able to test a 4.18 or later kernel?
